7.22.3 Dimensioning strategies
The diagram below shows the basic procedure for dimensioning a winding drive. DSD automatically
guides you through the required dimensioning steps.
[7-232] Strategy for dimensioning a winding drive in DSD
Calculation of the
physical values
(M, n, P)
Select motor
Select inverter
Select gearbox
Motor type (asynchronous, synchronous,
frame size, weight, enclosure, servo,
standard)
Select low rated speed for high field
weakening (e.g. 29-Hz technology)
Gearbox yes/no
Field weakening factor k
f
< winding ratio q
(the greater k
f
, the lower the motor/inverter
power)
Mechanical requirements
Ambient conditions
